Mounjaro vs Ozempic: Which Costs More?

TL;DR

• Both Mounjaro and Ozempic cost over $1,000 per month at list price, but savings cards can reduce cost to $25 per month with commercial insurance.

• Without insurance, Ozempic currently offers a lower self-pay option at $349 per month compared to Mounjaro's retail price of $1,000 or more.

• Mounjaro shows slightly greater weight loss and blood sugar improvements in clinical trials, which may factor into value for cost decision.

What Do They Cost Without Insurance?

Without any insurance or discount programs, both medications cost over $1,000 per month at retail pharmacies.

Mounjaro (tirzepatide) has a list price of approximately $1,069 to $1,080 per month for a four-week supply. Retail pharmacy prices can range from $1,100 to $1,500 depending on your location and specific pharmacy. All dose strengths (2.5 mg through 15 mg) are priced similarly, so moving to higher maintenance dose does not significantly increase your monthly bill.

Ozempic (semaglutide) has a list price of roughly $935 to $1,000 per month. In late 2025, Novo Nordisk introduced a cash-pay program that lowered out of pocket cost for self-pay patients to $349 per month after an introductory period. This makes Ozempic meaningfully cheaper than Mounjaro for people paying entirely out of pocket.

For tirzepatide specifically, Eli Lilly's self pay pricing is focused on Zepbound ( weight loss version) rather than Mounjaro (the diabetes version). Zepbound vials through LillyDirect start at $299 to $449 per month, but Mounjaro does not currently have same direct to consumer discount structure.

What Do They Cost With Insurance?

With commercial insurance that covers either medication, both become much more affordable. Both Eli Lilly and Novo Nordisk offer manufacturer savings cards that can reduce your copay to as low as $25 per month for eligible commercially insured patients.

Mounjaro's savings card covers up to $1,300 in annual savings and allows up to 13 fills per year. If your insurance covers Mounjaro, the card brings your copay to $25 for a one-month or three-month supply.

Ozempic's savings card works similarly, reducing out-of-pocket costs to as low as $25 per month for eligible patients with commercial coverage. The card also covers up to 13 fills per year.

If your commercial insurance does not cover one of these medications, savings card can still help, but discount is smaller. For Mounjaro, card may bring cost down to around $499 per month for pen. For Ozempic, manufacturer program offers different tiers depending on your specific situation.

Medicare and Medicaid patients are not eligible for either savings card. Federal law prohibits manufacturer coupons from being used with government insurance programs. Both medications may be covered under Medicare Part D for type 2 diabetes with prior authorization, but coverage for weight loss is generally excluded.

How Do They Compare on Effectiveness for Price?

Mounjaro tends to produce slightly better results in clinical trials, which is worth considering when comparing value for money.

In head-to-head research, tirzepatide (Mounjaro's active ingredient) led to an average weight loss of about 20% compared to about 14% for semaglutide (Ozempic's active ingredient) over similar treatment periods. Mounjaro also showed slightly greater blood sugar reductions in diabetes trials. This dual-action mechanism, targeting both GIP and GLP 1 receptors, is what drives the difference.

Both medications are FDA approved for type 2 diabetes. Ozempic has an additional approval for reducing cardiovascular risk and, as of 2025, for slowing kidney disease progression. Mounjaro does not have these additional cardiovascular or renal indications yet. You can review FDA approved uses and safety information for both on FDA Mounjaro prescribing label.

How Can You Lower Cost of Either One?

A few strategies work for both medications.

Use the manufacturer savings card if you have commercial insurance. This is the single biggest cost reducer for most people. Compare pharmacy prices. Warehouse stores like Costco, Walmart, and Sam's Club often offer lower prices than chain pharmacies. You do not need a membership to use Costco's pharmacy. Ask about 90-day supplies. Some insurance plans and pharmacies offer a lower per-unit cost when you fill three months at once. Check if your insurance requires step therapy. Some plans will only cover Mounjaro or Ozempic after you have tried a cheaper medication like metformin first. Understanding this requirement upfront can prevent delays in getting your preferred drug covered.

Conclusion

Mounjaro and Ozempic cost roughly the same at list price, both exceeding $1,000 per month. With insurance and savings cards, both can drop to $25 per month. Without insurance, Ozempic currently offers a lower cash pay option at $349 per month, while Mounjaro's self pay discounts are focused on Zepbound rather than Mounjaro itself. Mounjaro shows slightly better weight loss and blood sugar results in trials, which may justify price difference for some patients. The best choice depends on your insurance coverage, your medical needs, and which savings programs you qualify for.
